small simplications to powpowcontroller
Add callback when all sounds have loaded
make all common css prefixed with hft
fixes for css hft prefix change
remove msg area from powpow
Fix plistmanager for powpow show it shows correct ships
add games.html games menu.

This makes it easier to check out the games. On one machine you
go to http://localhost:8080/games.html, pick a game, if you want
to switch games press back in the browser, pick another.

Players go to http://localhost:8080/

I worry a little that if a player is paying attention to the URL bar
they'll see the URL and go to that page and mess up stuff. See
issue in todo.md
fix type on gamemenu.item.html
Make controllers go to main menu or reload after disconnect
make jamjam controller save rhythm in cookie
Make cookie library be an object so it saves the name.

Old way

    var value = Cookies.readCookie("foobar");
    Cookies.createCookie("fooobar", value, 90);  // <! ERROR! Wrong name

New way

    var foobarCookie = new Cookie("foobar");
    var value = foobarCookie.get();
    foobarCookie.set(value, 90);

Now I can't get the name wrong when reading vs writing. DRY FTW!
